T-25 No Spark

My t-25 just went out on me. No spark. Checked wires/conectors all seem fine. Changed plug/cleaned the toggle switch w. electro cleaner. Still no action. On last use I noticed it had a hard time shutting off. Took a couple tries on the switch to shut down, now it won't start. Help please, as this ol hummer will rip if it only starts.

In front of the carb is an electrical connection covered in plastic
where 3 wires come together. One to the on/off switch, one to
the ignition module below the carb, and the other one to the
coil under the engine cover. Disconnect the one going to the
on/off switch and leave the other 2 connected and see what
happens. The wire to the switch could be broken and is now touching the metal of the trimmer thus grounding your coil.
